Use lookup table for /\b{gcb}/ instead of switch stmt
This changes the handling of Grapheme Cluster Breaks to be entirely via
a lookup table generated by regen/mk_invlists.pl.
This is easier to maintain and follow, as the generation of the table
follows the text of Unicode's UAX29 precisely, and loops can be used to
set every class up instead of having to name each explicitly, so it will
be easier to add new rules. And the runtime switch statement is
replaced by a single line.
My gcc compiler optimized the previous version to an array lookup, but
this commit does it for not so clever compilers.
